Abstract

A shorted diode protection system for a brushless alternating current generator of the type having an energizeable exciter field winding 36 includes a circuit arrangement 55 for sensing the voltage differential across the exciter field and pairing the voltage differential with generator load current measured at 26 to provide an output signal that falls within a predictable range of values over a normal generator load current range. The output signal is of such a nature that it falls within a higher range of values upon the occurrence of a shorted diode. Another circuit arrangement 65 is responsive to the output signal such that whenever the output signal exceeds a preset value over the normal load current range, an output is generated that operates to cause the interruption of the exciter field. <IMAGE>
